Testing the Modularity of Memory. Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources.

Researchers disagree about whether verbal and visual working memory (WM) storage occurs in separate modules. Recent evidence suggests that only verbal memoranda have access to a specialised module, while visual memories make use of more general resources. This project aims to re-examine interference between verbal and visual memoranda using statistical methods specialised for assessing whether multiple latent factors underlie performance on recognition memory tasks, examining adult and child populations. This is expected to influence applications of WM theory in many everyday settings, resulting in improvements in educational practices, workplace procedures, and clinical treatments that depend on theoretical understandings of limits in cognition.Read moreRead less

Cracking the code of successful language learning. Mastery of a second language generates economic advantages, especially in English-speaking nations with large immigrant populations, such as Australia. It is not clear why some second-language learners flourish while others struggle in the same educational setting.

Mastery of a second language generates economic advantages, especially in English-speaking nations with large immigrant populations, such as Australia. It is not clear why some second-language learners flourish while others struggle in the same educational setting. Successful learners must possess attributes that when combined with the features of the learning situation result in positive learning outcomes, whereas unsuccessful learners are likely mismatched to their training method. In a series of artificial language learning experiments, this project aims to identify the combination of factors that matter most in successful language learning. Ultimately it may be possible to tailor training proactively to maximise learning outcomes.Read moreRead less
Tracking reading comprehension: What experts reveal about the mind. This project plans to use expert readers to provide a window on what defines optimal reading. Reading is a complex skill that requires precise coordination of cognition, perception and attention.

This project plans to use expert readers to provide a window on what defines optimal reading. Reading is a complex skill that requires precise coordination of cognition, perception and attention. By measuring skilled readers’ eye movements while they read sentences and short passages, the experiments are designed to investigate how individual differences in reading, spelling and vocabulary influence the timing and coordination of word identification and comprehension processes during normal reading and how this changes with a readers' goals. The results would distinguish between competing theories of how skilled readers balance word identification and comprehension processes, an issue that is critical to current debates about how reading should be taught.Read moreRead less
Cracking the code for skilled reading: the role of lexical quality in word and sentence reading. This project tests the hypothesis that highly skilled reading depends on precisely specified stored knowledge about written words. This project will investigate how individual diffences in reading, spelling and vocabulary among expert readers influence the time course of early orthographic and semantic processes in word identification and the pattern of lecical and contextual influences on eye moveme ....Cracking the code for skilled reading: the role of lexical quality in word and sentence reading.

Explaining the native-language listening advantage by charting neural response and perceptual adaptation across languages – but within individuals. Listening to the native language is easier than listening to a second language. This advantage is especially clear in recognising voices and in listening in noise. Identifying talkers was recently shown to involve rapid perceptual adjustment to their speech sounds, and successful listening in noise to involve adjustment of word recognition processes. ....Explaining the native-language listening advantage by charting neural response and perceptual adaptation across languages – but within individuals. Listening to the native language is easier than listening to a second language. This advantage is especially clear in recognising voices and in listening in noise. Identifying talkers was recently shown to involve rapid perceptual adjustment to their speech sounds, and successful listening in noise to involve adjustment of word recognition processes. This project tests the prediction that listeners more efficiently deploy each type of adjustment in the native than in a second language, by comparing native with second language phonetic and lexical processing within individuals. Further, a novel fMRI method in which target brain regions are defined functionally in each subject will identify the neural basis of the native listening advantage.Read moreRead less
Tracking towards a complete model of skilled reading comprehension. This project aims to promote the development of the first complete computational model of reading comprehension. Many computational models of sub-components of reading have been developed, but none fully explain the complex co-ordination of perceptual, attentional and cognitive processes required for successful comprehension. The project intends to use eye tracking studies to test and refine Über-Reader, a new computational mode ....Tracking towards a complete model of skilled reading comprehension. This project aims to promote the development of the first complete computational model of reading comprehension. Many computational models of sub-components of reading have been developed, but none fully explain the complex co-ordination of perceptual, attentional and cognitive processes required for successful comprehension. The project intends to use eye tracking studies to test and refine Über-Reader, a new computational model that aims to provide a complete account of the memory systems and cognitive processes involved in reading comprehension and how they differ with reading skill. The outcomes will advance understanding of the causes of success and failure in reading and contribute to diagnosing and remediating reading difficulties.Read moreRead less
Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how ....Comprehending text: A natural laboratory for investigating cognitive ageing. This project aims to determine whether the cognitive processes required for reading comprehension change in old age. Reading is a complex skill that requires precise co-ordination of perception, cognition and attention but appears relatively immune to age-related declines that impair performance in other complex cognitive tasks. Sophisticated eye tracking and electrophysiological studies will be analysed to specify how older adults adapt to the sensory and neural impairments associated with age. The outcomes will advance theories of cognitive ageing and reading comprehension and contribute to development of novel interventions to predict and enrich cognitive capacities in old age.Read moreRead less

Summary
Neural mechanisms of inhibitory control of human speech in stutterers and non-stutterers. Stopping oneself from speaking is a crucial communication function. In people who stutter, a disorder of this function causes their debilitating speech problem. This project will use cutting edge neuroimaging techniques to reveal how the brain stops speech in stutterers and in fluent speakers.
Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify ....Beyond Speech: Towards better communication for children with hearing loss. Despite the benefits of early newborn hearing screening and early intervention programs for children with hearing loss, most still experience academic and social challenges at school. This is partly due to ongoing listening effort, leading to communicative breakdown. This project aims to identify the locus of the communicative challenges these children face during daily discourse interactions. The outcomes will identify which levels of language are most compromised and will inform future interventions to reduce children’s listening effort. This will be undertaken by bringing together researchers in basic science with hearing service providers, parents and industry, providing an innovative model for solving multidisciplinary challenges.Read moreRead less
